scp的风险意识

本文得到枯荣长老的大力指点，在此表示感谢。

man scp 
     -l limit
             Limits the used bandwidth, specified in Kbit/s

[root@rhel63single arch]# scp 1_143_807882551.dbf  192.168.80.175:/home/oracle/

然后在scp时加上速度限制：-l 1024 ,这个意思是说1024Kbit/s，也就是128KB/s

[root@rhel63single arch]# scp -l 1024  1_143_807882551.dbf  192.168.80.175:/home/oracle/
root@192.168.80.175's password:

[root@rhel63single arch]#
